C_(60)和C_(70)混合物甲苯溶液的吸收光谱及荧光光谱研究

Absorption and fluorescence spectral study of Fullerence-60 and Fullerene-70

测量了C_(60)和C_(70)混合物甲苯溶液的吸收光谱和荧光光谱.采用调QYAG激光器输出的倍频光(532nm)作为激发光,在670nm和695nm附近测量到了C_(60)和C_(70)混合物甲苯溶液的两个荧光峰,这些荧光峰有可能是由C_(70)分子产生的.

We have measured the absorption and fluorescence spectra from the solution of the mixture of C60 and C70 in toluene. The SHG output from a Q-switched YAG laser was used as excitation source. Two Fluorescence peaks were observed at circa 670nm and 695nm, which may originate from C70 molecules.
